Physical Immortality

Physical immortality.

Life extension is an area of technology that is going to sneak up on people. The sheer, seeming improbability of it is daunting; death seems like the single, immutable truth in life, the one dependable thing we can take for granted. While it may be depressing in many ways, death has always offered a sort of concreteness to the world, and attempts to thwart its advance are unanimously derided in science and science fiction alike.

Brilliant scientists, including Sergey Brin, co-founder of Google, thought it possible to someday "cure death," and Dmitry Itskov, the "godfather" of Russia's Internet, predicted that the technology that would allow him to live for 10,000 years would be in place by 2045. I grant that the technology

Death is a choice, and the only reason we die is because we believe that it is inevitable. The cause of death is said to be simply that we believe in it, I am of the firm belief that it is foolish to aspire for immortality. Do we need immortality? It would be a torture to live with the physical body with all the ailments, and the body not able to support all the systems. Probably with this imperfect body after a time one would be begging for relief in the form of death! It is not possible to live forever. Death is the final destination of the journey of life

Exactly how far and how fast life expectancy will increase in the future is a subject of some debate, but the trend is clear. An average of three months is being added to life expectancy every year and experts estimate there could be a million centenarians across world by 2030. To date, world's longest-living person on record lived to 122 and in Japan alone there were more than 44,000 centenarians in 2010. Some researchers say, however, that the trend towards longer lifespan may falter due to an epidemic of obesity now spilling over from rich nations into the developing

Biological forms have inherent limitations which may or may not be able to be overcome through medical interventions or engineering. Natural selection has developed potential biological immortality in at least one species, the jellyfish.

Certain scientists, futurists, and philosophers, such as Ray Kurzweil, advocate that human immortality is achievable in the first few decades of the 21st century, while other advocates believe that life extension is a more achievable goal in the short term, with immortality awaiting further research breakthroughs into an indefinite future. Aubrey de Grey, a researcher who has developed a series of biomedical rejuvenation strategies to reverse human aging (called SENS), believes that his proposed plan for ending aging may be implementable in two or three decades.

• Fame itself has been described as a method to "achieve immortality", if only semantically so that the name or works of a famous individual would "live on" after his or her death. This view of immortality places value on how one will be remembered by generations to come.

• The persistence of life itself across time is a form of immortality, insofar as leaving surviving offspring or genetic material is a means of defeating death. 'Don't fall for the cult of immortality'

Immortality is the power not to
